During a bone scan, you get a small amount of radioactive material called a "radionucleotide" (or tracer). Tissues like air and water have little attenuation and are displayed as low densities (dark), whereas bone has high attenuation and is displayed as high density (bright) on CT. In bone metastases this is at the repair surface due to osteoblastic activity in response to most adenocarcinomas and sarcomas.
